8 Channel Voltage to Modbus RTU.

The DAT10017-V is an 8-channel Modbus RTU/ASCII converter designed to acquire voltage signals and transmit them digitally over an RS-485 network. It supports voltage inputs up to ±10 V, converting them into engineering units for PLCs, SCADA systems, and other Modbus master devices.

Key Features

• 8 independent analog voltage input channels, supporting up to ±10 V.
• Programmable scaling of input values up to ±32768 points for precise engineering units.
• High accuracy and long-term stability across varying temperature and environmental conditions.
• Integrated Watchdog timer alarm for enhanced plant safety.
• 1500 Vac isolation between circuit parts to eliminate ground loops and ensure reliable operation.
• Compact, self-extinguishing plastic enclosure, suitable for DIN rail mounting (EN-50022 standard).

Communication Protocols

The DAT10017-V communicates using Modbus RTU or Modbus ASCII over RS-485. This allows seamless integration with most PLCs, SCADA systems, and Modbus-compatible applications. For protocol commands, consult the User Guide.

User Instructions

The device can be configured either by DIP switches located on the front panel or via PC software using INIT mode. To enter INIT mode, connect the INIT terminal to REF at power-on; the device will automatically switch to configuration setup (see the User Guide for details).

Power supply, RS-485 bus, and input connections are wired as shown in the “Wiring” section. LED indicators provide real-time status feedback (refer to the “Light Signalling” section). Terminals are removable even while powered, simplifying maintenance or replacement.
